What is Total Quality Management (TQM)?

500

What is the purpose of the Control phase in the DMAIC process

The Control phase ensures that the improvements made during the project are sustained over time. It involves implementing control plans, monitoring performance, and preventing regression to the old process

500

What is the difference between Type I and Type II errors in hypothesis testing?

Type I error (false positive) occurs when we reject a true null hypothesis, while Type II error (false negative) occurs when we fail to reject a false null hypothesis.

500

Who introduced the concept of Total Productive Maintenance (TPM) as part of Lean practices?

Seiichi Nakajima is credited with developing TPM, which aims to maximize equipment effectiveness and minimize downtime.

500

Which Lean principle emphasizes reducing setup times and increasing flexibility in production?

The Principle of SMED(Single-Minute Exchange of Die focuses on minimizing changeover times between different product runs or setups.

What is the purpose of a Design of Experiments (DOE) in Six Sigma?

DOE helps identify the critical factors affecting a process and their interactions. It allows experimentation to optimize process performance3.
